Because your kernel module and afsd aren't built with the USE_FH option, =
which enables support for filesystems which have complex file =
descriptors. We turn on USE_FH when the kernel doesn't offer us the =
iget() function - iget() disappeared around 2.6.25.

So, tmpfs is supported, but only with kernels later than 2.6.25
